RAGGLB BLOCK Filed July 5, 1929 Patented Feb. 13, 1934 PATENT OFFICE RAGGLE BLOCK Jones P. Stagg, Wyoming, Ohio, assignor to The Philip Carey Manufacturing Company, a corporation of Ohio Application July 5, 1929. Serial No. 376,002

4 Claims. 10826) My invention relates to raggle blocks for roofing and is particularly adapted for use in brick walls or other like construction such as concrete. It is addressed to providing a weather-proof non- 5 deteriorating raggle block that will hold the flashing strip fixedly secured in place preventing any slippage, and may be readily installed by the workmen building the wall.

My improved flashing block is preferably placed in the wall during the building of the wall, the wall being built around three sides of it and then when the roof is being applied the upper member of the raggle block may be readily removed, the ends of the flashing strip placed over the lower section and the first mentioned section replaced forming a wedge and locking the roofing firmly between the two members of the raggle block in the wall as hereinafter explained.

In the drawing forming part hereof, Fig. 1 is a cross section showing the two members of my improved raggle block slightly separated to illustrate where the flashing strip is placed between them, and Fig. 2 illustrates the block in wall holding the flashing strip in place.

My improved raggle block consists of two sections A and B having longitudinally extending grooves C separated by tongues D. The block member A is preferably slightly wider than the lower block member B so as to form when in place an overhang or drip face. The two block members A and B are provided with longitudinally extending corrugations E, E on their adjacent faces. The grooves C, C; the tongues D, D and the corrugations E, E may be of any suitable form to serve the purposes hereinafter set forth.

My improved raggle block is preferably formed from a homogeneous mixture composed of a bituminous material, a fibrous material and a granular mineral material mixed and moulded in any suitable way under pressure so as to form a relatively rigid, yet plastic board like material.

In Fig. 2 I have shown my raggle block in use in a brick fire wall. In practice the bricklayer lays the raggle block longitudinally along the side of the wall adjacent to the roof structure, placing between the two members of the raggle block, in the space shown in Fig. 1, small pieces of wood so that the space between the two raggle block members formed by the wood allows the member A when the wood pieces are removed to drop permitting the withdrawal of member A. F is the flashing; H the roof and G the cant strip. The member A having been removed, the flashing strip is applied over the surface of the lower member B the block and is fixed by cementing or nailing or both to the surface of the member B. Then the upper raggle block member A is forced back by tamping into position so that it is wedged between the lower block A, the edge of the flashing strip and the underside of the brick forming the top of the raggle block cavity. The corrugation E on the member A as it is forced into position interlock with the adjacent corrugations E on the block B and prevents any slippage of the top section out of the raggle block space. This wedging of the two members of the raggle block in the space with the flashing between them tends to lock the flashing strip in place shown by reason of the pressure thereby created and the character of the materials from which the blocks are formed which creates a high degree of friction between the blocks and the flashing strip and the adjacent wall portion, this latter is increased by the tongue D and grooves C. If desired the surface of the wall space in which the block is placed could be coated with bituminous material such as asphalt by mopping it on the underside of the brick forming the top, back and bottom of the cavity in which the block is placed. The groove C and the tongue D on the two members tend to interlock by friction with the adjacent surfaces of the brick and assist in holding the raggle block in fixed position on the wall.

I claim:

1. A raggle block composed of two members, each of said members provided with surfaces adapted to be brought adjacent to each other and to enclose between them a flexible sheet material, each of said surfaces provided with a plurality of longitudinally extended grooves and tongues so arranged that the grooves and tongues of opposite members register, whereby the members are prevented from independent transverse movement when the block is assembled.

2. In a roof structure, a wall, a raggle block in said wall, said raggle block composed of two members, each of said members in contact with a portion of said wall and with each other, the adjacent faces of said members provided with interlocking means preventing independent transverse movement of either of said members.

3. In a roof structure, a wall, a raggle block in said wall, said raggle block composed of two members, each of said members in contact with a portion of said wall and with each other, the ad- 105 jacent faces of said members provided with interlocking means preventing independent transverse movement of either of said members, a flashing strip held in place between the said adjacent faces of said members,

4. In a roof structure, a wall, a raggle block in said wall, said raggle block composed of two members, each of said members in contact with a portion of said Wall and with each other, the

5 adjacent faces of said members provided with interlocking means preventing independent trans-
